Sawmills in the Canadian province of Alberta were surveyed in order to identify occupations at greatest risk and to guide compliance measures. Two hundred and ten wood dust samples (inhalable) were collected from nine Alberta sawmills using Institute of Occupational Medicine (IOM) personal samplers. Nine percent of samples exceeded 5 mg/m(3) 8-hour time-weighted average (TWA) for total dust. There was a significant statistical difference (p < .001) between the median and geometric mean inhalable particulate matter (IPM) dust levels for 4 aggregated occupational groups. Levels were highest for cleanup workers (3.5 mg/m(3)), followed by the maintenance, planermill, and sawmill occupational groups, as were other measures of dust levels. In response to these findings, the Alberta Forest Products Association undertook a program to train sawmill managers to implement these recommendations on engineering controls, administrative controls, and personal protective equipment.
为了确定风险最大的职业并指导合规措施，对加拿大艾伯塔省的锯木厂进行了调查。使用职业医学研究所（IOM）的个人采样器，从艾伯塔省的9家锯木厂收集了210份（可吸入）木尘样本。9%的样本总粉尘8小时时间加权平均（TWA）超过5毫克/立方米。4个汇总职业组的可吸入颗粒物（IPM）粉尘水平的中位数和几何平均数之间存在显著统计学差异（p < .001）。清理工人的粉尘水平最高（3.5毫克/立方米），其次是维护、刨床和锯木厂职业组，其他粉尘水平指标也是如此。针对这些调查结果，艾伯塔省林产品协会开展了一个项目，培训锯木厂经理实施关于工程控制、行政控制和个人防护设备的这些建议。
